There were also several interesting developments in injection molding control and monitoring systems at this past April’s NPE2012 exhibition in Orlando, Fla.

In plastic injection molding, the primary objective is to manufacture dimensionally and structurally consistent parts, independent of the molding machine being used.

Hot buttons at the show will be multi-component molding, in-mold labeling/decorating (IML/IMD), in-mold assembly, medical molding, liquid silicone rubber (LSR), micro-molding, and high-speed packaging.

WEB EXCLUSIVE: Two new temperature-based control programs to address flow balancing in hot-runner systems have been added to the Priamus Fill controls from Priamus System Technologies LLC., Brunswick, Ohio.

A new process-monitoring system that utilizes PC-based Process Data AcquisitionModules (PDAM) was shown at NPE 2009 by Syscon-PlantStar, SouthBend, Ind.

Cavity pressure and temperature sensors can be checked to confirm proper operation with a new signal tester from Priamus System Technologies LLC., Brunswick, Ohio.

A new line of cavity temperature sensors that do not contact the injection molded plastic is new from Priamus System Technologies LLC, Brunswick, Ohio.

A new control option that combines injection machine control with cavity-pressure/temperature sensing and control comes from Keba AG, Linz, Austria, and Priamus System Technologies LLC., Brunswick, Ohio.

The accepted ground rule for balancing melt flow in multi-cavity injection molds is to achieve equal flow distance from the injection point to each cavity.

Vernay Laboratories Inc. of Yellow Springs, Ohio, is a major producer of precision rubber fluid-control components at four plants in the U.S. and Europe. “In rubber molding, the temperature of the mold is the heart of the process, so maintaining a uniform thermal profile across the tool is vital,” says Ankur Maheshwari, program manager at the Griffin, Ga., plant, Vernay’s biggest in North America.The company was having a big problem controlling temperature uniformity in production of a special gasket seal used in printer cartridges.

WEB EXCLUSIVE A new line of waterproof injection molding cavity temperature sensors, which allow it to be mounted in the cooling circuit, is new from Priamus System Technologies LLC, Brunswick, Ohio.

A new injection machine control and monitoring system that allows molders to attain similar production rate and part quality from a mold as it moves from machine to machine was introduced at the K Show in Germany last month by Priamus System Technologies LLC., Brunswick, Ohio.

Miniature cavity-pressure sensors have been added to the Priasafe line from Priamus System Technologies LLC, Brunswick, Ohio.

Monitoring and control of the operation of rotary-table molds is a new option on the Priamus Monitor data-acquisition system from Priamus System Technologies LLC., Brunswick, Ohio.

A new process information system that combines comprehensive process monitoring from each injection machine with central data collection is new from Priamus System Technologies LLC, Brunswick, Ohio.

For small molds, new miniature cavity-pressure sensors are said to be easier to install than previous mini sensors.

Web-based or wireless monitoring, combined temperature and pressure sensing, cost-saving modularity, and better ways to display and report process and production data are some of the advances in control and monitoring that will be presented at this year’s NPE.One development that could have the broadest implications is Watlow’s new EZ-Zone ST modular “integrated architecture” for temperature control loops.
